Problem is resolved when the sonar.jacoco.reportPath property is added to the pom.xml (line 6):
<properties>
<java.version>1.8</java.version>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<!-- this is defined in spring-core-env and fits for multi module project. Scanner fails for single module projects! -->
<sonar.jacoco.reportPath>${project.basedir}/target/jacoco.exec</sonar.jacoco.reportPath>
</properties>
